DART 0R ARROW.

Specification of Letters Patent.

Patented NOV. 30, 1915.

Application filed September 13, 1915. Serial No. 50,284.

T 0 all whom it may concern:

Be it known that I, Mwron E- WINANS, av citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Darts or Arrows, ofwhich the following is a full, clear, and exact description.

This invention relates to darts or arrows to be dropped from aeroplanesor other aircraft upon hostile troops below, and its object, brieflystated, is to provide an improved dart that can be manufactured at lesscost of time and material than the prior devices.

To this and other ends the invention comprises the novel featureshereinafter described.

One form of the invention is illustrated in the accompanying drawings,in which- Figure 1 shows the completed dart in perspective. Fig. 2 is aperspective view on a larger scale showing the crossed feathers and themode of assembling the same. Fig. 3 is a perspective view of the head ofthe dart, showing the crossed slots in its butt or rear end forreceiving the ends of the feathers. Fig. 4. is a perspective viewillustrating a convenient method of securing the ends of the feathers inthe slots in the head. Fig. 5 is a perspective view illustrating thefastening of the outer or rear ends of the feathers together by spotwelding, as by means of an oXy-acetylene flame.

The dart, as illustrated in Fig. 1. comprises a pointed metal head 10,usually cylindrical, into the butt end of which are fastened two crossedmetal feathers 11, 12, each being of the same width as the diameter ofthe head. The feathers are provided with oppositely extending, centrallongitudinal slots 13, 14, respectively, so that the two feathers can beassembled by straddling, or by sliding one into the other, as clearlyindicated in Fig. 2. The feather 12, which has its slot extendingupwardly from the lower end, is slightly longer than the other.

In the butt or upper end of the head 10 are two crossed slots 15, 16, atright angles to each other, to receive the lower ends of the feathers,slot 16 being the deeper to acsquare, but preferably they have theircorners clipped off, as shown.

Heretofore, in darts for the purpose mentioned, the feathers have beenmade by milling qu'adrantal-shaped recesses in the sides of a solid barof metal. The metal thus cut from the bar in the form of chips is ofcourse wasted, and moreover the operation requires considerable time ifdone with the requisite accuracy. In my improved dart this loss isavoided, practically the only Waste of that kind being the negligibleamount of metal lost in sawing the slots in the head, and moreover thetotal time consumed in making the dart is considerably less. The netsaving on a single device is of course small, but darts for this purposeare made by the million and the aggregate saving thus becomes important.

It is to be understood that the invention is not limited to the exactconstructionherein illustrated and described, but can be embodied inother forms Without departure from its spirit.

I claim:

1. A dart or arrow comprising a metal head having crossed slots in itsbutt end, and crossed feathers consisting of sheet metal strips slottedlongitudinally from their opposite ends and slid together, the feathersbeing inserted into said slots and suitably fastened in place.

2. A dart or arrow comprising a metal head having crossed slots in itsbutt end, one slot being deeper than the other; a feather consisting ofa strip of sheet metal having one end inserted in the shallower slot andhaving a-longitudinal slot extend ing from the other end; and a similarfeather similarly slotted, crossing the other in the slot in the latterand having its slotted end inserted into and fastened in the deeper ofthe slots in the head.

. 3. A dart or arrow comprising a metal head having crossed slots in itsbutt end,

crossed feathers composed of slotted sheet metal strips straddling eachother and inserted at one end into the slots in the head, the feathersat the other end being spotwelded together. a

4. A dart or arrow comprising a metal head having crossed slots in itsbutt end,

one deep and the other shallow; a strip of sheet metal havlng one endinserted in the shallow slot and havinga longitudinalcentral slotextending inwardly from the other end; and-a centrally slotted strip ofsheet metal straddling the other crosswise 'and having its slotted endinserted and checkfastened in the deep slot in the head; the outer ends.of the two crossed strips being spot-welded together.

In testimony whereof I have hereunto 20 aflixed my signature.

MILTON E. WINANS.
